The website of the Home Ministry was non-functional on Sunday and officials said experts were finding out if it had been hacked.
The website's landing page is drawing a blank and the site itself has become inaccessible. The problem most probably began early in the morning.
"I don't know when the site developed the snag," ministry spokesperson KS Dhatwalia told IANS. "Details will be available after we find out the glitches.
"We are checking," Dhatwalia said, adding he was not sure when the website would become functional.
The spokesperson had earlier said it was not a case of hacking as the site was being reconstructed.
The MHA website was immediately blocked by the National Informatics Centre after hacking was noticed.
Last month, suspected Pakistan-affiliated operatives had hacked the official website of the elite National Security Guard (NSG) and defaced it with a profanity-laden message against the Prime Minister and anti-India content.
More than 700 websites of various central and state government departments were hacked in the past four years and a total of 8,348 persons were arrested for their involvement in cyber crimes, according to official data released this month.
